Subject: Complementing tomato trichome mutants

Abstract: Growth and development of new tissues and structures requires control of protein abundance in a cell type specific pattern. Glandular trichomes of tomato (S. lycopersicum) are special structures that are important for insect defense due to their unique production of high concentrations of volatile terpenoids. We are studying a tomato mutant named odorless-2 (od-2) which has several developmental irregularities including small leaflets, reduced trichome abundance, and importantly an absence of terpenoid production. Interestingly od-2 has revealed a necessity for sphingolipid production to support not only normal leaf development but also accumulation of terpenoids. The conservation of sphingolipid production amongst all eukaryotes means this work could have deep implications in other systems.
